[1] These parameters are guaranteed by design and are tested only by sampling while mass production. [2] While a voltage source with large output impedance is measured by an instrument-ation amplifier having input bias current, an additional input offset voltage will introduced. However, this offset voltage could be cancelled by mirrored offset cancellation technique.
